Liquid crystal display module

Abstract

A liquid crystal display (LCD) module includes a liquid crystal display panel having upper and lower substrate with a liquid crystal layer interposed therebetween. A backlight unit is arranged under the liquid crystal display panel. The LCD module includes an upper frame and a lower frame. The upper frame has a horizontal portion and a vertical portion, the horizontal portion pressing an edge of the liquid crystal display panel and having at least one fixing hole. The lower frame has a side wall portion and a bottom portion and accommodates the liquid crystal display panel. The bottom portion of the lower frame supports the backlight unit, and the side wall portion has at least one protruding portion at a location corresponding to the fixing hole of the upper frame.

       a second frame having a side portion and a bottom portion and accommodating the liquid crystal display panel, the bottom portion supporting the backlight unit, the side portion having at least one protruding portion at a location corresponding to the fixing hole of the first frame.  
     
     
       2. The liquid crystal display module of  claim 1 , wherein the first portion is a horizontal portion of the first frame and has a bent portion, the bent portion having the fixing hole. 
     
     
       3. The liquid crystal display module of  claim 1 , wherein the fixing hole of the first frame and the protruding portion of the second frame have a substantially rectangular shape. 
     
     
       4. The liquid crystal display module of  claim 1 , wherein the first frame is made of a metal. 
     
     
       5. The liquid crystal display module of  claim 4 , wherein the first frame is made of stainless steel. 
     
     
       6. The liquid crystal display module of  claim 1 , wherein the second frame is made of polyethylene terephthalate. 
     
     
       7. The liquid crystal display module of  claim 1 , wherein the first frame is an upper frame and the second frame is a lower frame. 
     
     
       8. The liquid crystal display module of  claim 1 , further comprising a polarization layer on the first substrate. 
     
     
       9. The liquid crystal display module of  claim 1 , further comprising a polarization layer on the second substrate. 
     
     
       10. The liquid crystal display module of  claim 1 , wherein the backlight unit includes a plurality of optical sheets and a light guide plate. 
     
     
       11. A liquid crystal display module comprising: 
       a liquid crystal display panel having first and second substrates with a liquid crystal layer between the first and second substrates;  
       first and second polarization layers on the first and second substrates, respectively;  
       a backlight unit adjacent the liquid crystal display panel;  
       an upper frame having a horizontal portion and a vertical portion, the horizontal portion pressing an edge of the liquid crystal display panel and having at least one fixing element; and  
       a lower frame having a side wall portion and a bottom portion and accommodating the liquid crystal display panel, the bottom portion supporting the backlight unit, the side wall portion having at least one protruding portion at a location corresponding to the fixing element of the upper frame.  
     
     
       12. The liquid crystal display module of  claim 11 , wherein the horizontal portion of the upper frame has a bent portion, the bent portion having the fixing hole. 
     
     
       13. The liquid crystal display module of  claim 11 , wherein the fixing hole of the upper frame and the protruding portion of the lower frame both have a substantially rectangular shape. 
     
     
       14. The liquid crystal display module of  claim 11 , wherein the upper frame is made of a metal. 
     
     
       15. The liquid crystal display module of  claim 14 , wherein the upper frame is made of a stainless steel. 
     
     
       16. The liquid crystal display module of  claim 11 , wherein the lower frame is made of polyethylene terephthalate. 
     
     
       17. A method of assembling a liquid crystal display module comprising: 
       providing a liquid crystal display panel having first and second substrates with a liquid crystal layer between the first and second substrates;  
       attaching a backlight unit adjacent the liquid crystal display panel;  
       attaching an upper frame having a horizontal portion and a vertical portion, the horizontal portion pressing an edge of the liquid crystal display panel and having at least one fixing element; and  
       attaching a lower frame having a side wall portion and a bottom portion and accommodating the liquid crystal display panel, the bottom portion supporting the backlight unit,  
       wherein the side wall portion has at least one protruding portion located corresponding to the fixing element of the upper frame.  
     
     
       18. The method of  claim 17 , further comprising forming first and second polarization layers on the first and second substrates, respectively. 
     
     
       19. The method of  claim 17 , wherein the horizontal portion of the upper frame has a bent portion, the bent portion having the fixing hole.
